Question How Do I Clamp the Camera?

I am making an arcade car game and I want to clamp the camera.. how do I do it? this is my script

Code (CSharp):

1. [Header("Main Stuff")]
2.         public float sensitivity = 0.25f;
3.         public float minVal = -60f;
4.         public float maxVal = 60f;
5.         public GameObject theCar;
6.         public GameObject camHolder;
7.        
8.         float _mouseX;
9.         float _mouseY;
10.         Camera _cam;
11.        
12.         void Start()
13.         {
14.             _cam = Camera.main;
15.         }
16.  
17.         void Update()
18.         {
19.             MouseInput();
20.             CamHolderPosition();
21.             CamHolderRotation();
22.             CamLocalPos();
23.  
24.         }
25.  
26.         void MouseInput()
27.         {
28.             _mouseX = Mouse.current.delta.ReadValue().x * sensitivity;
29.             _mouseY = Mouse.current.delta.ReadValue().y * sensitivity;
30.         }
31.  
32.         void CamHolderPosition()
33.         {
34.             Vector3 carPos = theCar.transform.position;
35.             camHolder.transform.position = new Vector3(
36.                 carPos.x,
37.                 carPos.y,
38.                 carPos.z);
39.         }
40.  
41.         void CamHolderRotation()
42.         {
43.             Quaternion camHolderRot = camHolder.transform.rotation;
44.             Quaternion rot = Quaternion.Euler(camHolderRot.eulerAngles.x - _mouseY * sensitivity / 2,
45.                 camHolderRot.eulerAngles.y + _mouseX * sensitivity,
46.                 camHolderRot.eulerAngles.z);
47.  
48.             camHolderRot = Quaternion.Slerp(transform.rotation, rot, 1f);
49.             camHolder.transform.rotation = camHolderRot;
50.         }
51.  
52.         void CamLocalPos()
53.         {
54.             Vector3 camLocalPos = _cam.transform.localPosition;
55.             if (!(_cam.transform.localPosition.z > -1f)) return;
56.             camLocalPos = new Vector3(camLocalPos.x, camLocalPos.y, -1f);
57.             _cam.transform.localPosition = camLocalPos;
58.         }

 

Hello @RayanAziz11. The CamLocalPos logic looks ok to me if your intention is to clamp the z position to less than or equal to -1. What's the problem you are seeing? One odd thing I notice is you have a cameraHolder but you are also directly modifying _cam. Is that the intent? If I drop the following script on my camera it clamps z to -1.

Code (CSharp):

1. using UnityEngine;
2.  
3. public class CameraClamp : MonoBehaviour
4. {
5.     public float zClamp = -1f;
6.  
7.     void Update()
8.     {
9.         if (transform.localPosition.z > zClamp) {
10.             transform.localPosition = new Vector3(
11.                 transform.localPosition.x, transform.localPosition.y, zClamp);
12.         }
13.     }
14. }

 

Camera stuff is pretty tricky... you may wish to consider using Cinemachine from the Unity Package Manager.

There's even a dedicated forum: https://forum.unity.com/forums/cinemachine.136/

 

Cinemachine is awesome
